Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158560, here are decompositions:

23 + 158537 = 158560
41 + 158519 = 158560
53 + 158507 = 158560
71 + 158489 = 158560
131 + 158429 = 158560
167 + 158393 = 158560
197 + 158363 = 158560
257 + 158303 = 158560

Showing the first eight; more decompositions exist.
